Answer:
Derealization
Step-by-step explanation:
Derealization is a situation that usually plays out when an individual suffers a panic attack. In this situation, the person feels uncertain about everything in his environment, including time, space, and the size of things. He feels as if he were in a trance and many things seem unreal to him. The experience usually occurs along with the panic attack and this makes the sufferer feel as if he were crazy.
When a person experiences this, it is recommended that he talks to a physician or loved one, who would reassure them. It lasts for the full length of the panic attack and the person undergoing it can still recognize senses.
